Babies understand the meaning of work

04.10.2017

It is known that young children perfectly understand causal relationships, and children here do not need a lot of statistics, just a few illustrative examples are enough. Already at the age of fifteen months, the child perfectly understands the connection between the effort expended and the result.

Psychologists from the Massachusetts Institute of Technology showed fifteen-month-old children how they themselves, that is, adult experimenters, tried to perform various actions: some tried to remove a toy frog from a box, others were engaged in removing a key chain from a key chain. Some of the experimenters completed the tasks quickly, while others, on the contrary, fumbled for a very long time, demonstrating how much energy it takes him to do it.

Then the children were given a musical toy that made different sounds when they pressed a button. The trick, however, was that the toy had two buttons: the first, which did not work - in plain sight, and the second, which just turned on the sounds and which was very well hidden. The children were shown in advance that the toy could play music, but they were not shown what to do with it, after which the toy was given to them.

For two minutes, the babies tried to get some sounds from her, and psychologists watched exactly how they would act. Finding the true button, we repeat, was almost impossible, but it was not the goal - the researchers were interested in how long the children would try to solve the problem themselves.

It turned out that if the child had previously seen an adult who spent a lot of effort for some goal, then the baby himself worked harder: before discarding the toy or asking for help from adults, such children pressed the wrong button twice as much compared to those who saw adults who achieved their goal easily.

It is curious that the efforts of children also largely depended on how an adult communicated with them: if he looked the child in the eyes, called him by name, generally communicated with him, then the child made more efforts regarding the toy. If the adult did not directly interact with the baby, then the child stopped trying to start the music earlier - however, the very effect of harder work following someone else's example did not disappear anywhere, it just became weaker.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Effective antimicrobial film for gadgets 19.07.2014

Fujifilm has developed an antimicrobial coating technology that provides approximately 100 times better protection against bacteria than current silver solutions.

The new technology is called Hydro AG. It is supposed to be used in protective films for LCD touch screens and touch panels of equipment used in medical and educational institutions, public places.

The basis of Hydro AG is a superhydrophobic plastic with ceramic microparticles, which includes an antibacterial agent that can gradually release silver ions. The manufacturer notes that Fujifilm's experience in the creation and production of photographic film and high-precision coating technology was useful in the development. The project involved Toyama Chemical, a company specializing in evaluating the effectiveness of antimicrobial coatings.

The principle of operation of antimicrobial coatings is based on the release of silver ions due to wetting of the agent containing them. Ions bind enzymes on the surface of microbes, rendering them harmless. Thus, to increase the efficiency of the coating, it is necessary to increase the number of silver ions. The Hydro AG film is made from a superhydrophobic material that is almost completely water repellent. Due to this, water acts only on the agent particles embedded in the film, getting not only on their surface, but also penetrating deep into, thereby increasing the yield of silver ions and the service life of the coating.

According to the results of the test, more than 99,99% of microbes die on Hydro AG film in an hour. For comparison: the rate of conventional film is approximately 99%.
